Orca's sinking boats, wolves eating ranchers, beavers flooding a housing development, those sound awesome to me and I've seen plenty of people celebrating such things on here.

The difference in basically every one of those cases is the perception of nature attacking the rich and powerful or directly fighting back against abusers (there are also stories about elephants that I've seen come up once or twice for that reason). That is not the same as killing "humans" in a generalized sense as a form of collective reprisal or whatever.

Nobody here was celebrating the climate change-induced glacier collapse that killed hundreds in Tibet.
